GMC Metriso 5000 DPI Insulation Reistance Tester

High Voltage Insulation Testing
The Metriso 5000 DPI  is suitable for non-destructive measurement of insulation resistance
in electrical systems, as well as in machines, transformers, cables and electrical equipment
utilized in, for example, locomotives, street cars and ocean going vessels with selectable test
voltages of up to 5kV.

Voltage Measurement to 1000V
Testing for absence of voltage at the device under test in systems of up to 1kV can be performed
with the voltage measuring range.Discharging Capacitive Devices Under TestCapacitive devices
under test such as cables and coils, which may be charged by the test voltage, are discharged by
the mea-suring instrument. The falling voltage value can be observed at the display.

Measurements per EN61557 Parts 1 and 2 (VDE0413)
Nominal current amounts to 1mA at a test voltage of 100V, 250V, 500V or 1000V.Highly Insulated
Measurement CablesThe highly insulated measurement cables are permanently con-nected for safety
reasons, and due to technical measuring con-siderations. Danger resulting from inadvertently disconnected
cables, for example in the event of charging caused by capacitive devices under test, is thus avoided.

Polarization Index
A polarization index test is recommended for electrical machines. This procedure involves expanded testing
of insulation resistance. DC measuring voltage from the METRISO®5000 D-PI is applied to the insulation for
a duration of 10 minutes. Measured values are documented after one minute, and after ten minutes. If the
insulation is good, the value measured after ten minutes is higher than the value measured after one minute.
The relationship between the two measurement values is the polarization index. Charged material within the
insulation is aligned due to the application of measuring voltage over a long period of time, resulting in polariza-tion.
The polarization index indicates whether or not the charged material contained in the insulation can still be
moved, thus allow-ing for polarization. This, in turn, is an indication of the condition of the insulation.

Data Management and Report Generation
The data of each measurement can be stored under a selected object number. Furthermore, a description
for this object can be entered via the keyboard of the optional PSI module (Feature I1).The data management
function allows for individual measurement data of a previously selected object to be displayed and to be
deleted if required, or for previously entered objects to be deleted.Depending on the number of stored objects
(max. 254), up to 1,600 measurements can be stored. The current memory occupancy is continuously
displayed as a bar graph.Report data can be printed out at an external printer with Cen-tronics interface
via PSI module (Feature I1) or via printer adapter DA-II (accessory).Furthermore, it is possible to create
report templates at a PC which can be downloaded to the test instrument.
